Science

• what is the opening or vent in the planet's crust?

  volcano
• it erupted within the last 10,00 years?

  active volcano
• it has not erupted within the historical times?

  inactive volcano
• when rocks become hot and a substance, thin and runny gases can escape easily from it?

  magma
• this serves as the reservoirs for molten rocks?

  magma chambers
• it's a pathways for the magma?

  vent
• this is molten rocks that oozes onto the earth's surface, can vary in temperature and viscosity?

  lava flows
• this can travel significant distances from the volcano before SOLIDIFYING?

  volcanic bombs
• lava dome grows over time as the lava accumulate
• eruption columns has a towering plume of volcanic ash, gases and other materials
• eruption clouds have billowing mases of volcanic gases, ash, and particles
• tephra's magma is thick and sticky, gases cannot escape easily
• it emits sulfur dioxide and nitrogen oxide acid rain
• lahar mixes with water from streams or snow and ice
• pyroclastic flow is a fast moving mixture of hot gas, volcanic ash, and fragmented rock
• fumaroles are the holes, crack or fissures on the surface near volcanos
• cracks can form due to tectonic stresses allowing magma to rise
• it is a tall mountain with a crater on top composite volcano
• flat and warrior's shield, it reaches a great distance from the crater

  shield volcano
• cinder cones volcano form steep slopes around their wide crater
• PIVOCS means?

  Philippine Institute of Volcanology and Seismology
• crust is thin
• mantle is thick, beneath the lithosphere
• inner core is solid
• outer core is liquid
• this is the state of the athmosphere at any particular time, it is short term?

  Weather
• this is long term, average weather of a particular part of the world at different times of the year?

  Climate
• what is the wind trades in the Philippines?

  hanging habagat and hanging amihan
• what is the causes of weather and climate?

  solar radiation
• what is the cause of global warming ?

  greenhouse gases
• climate change is the long term shifts in temperature and weather patterns
• stars contain mostly hydrogen with some helium
• High mass star have high energy and heavier
• low mass is less hot and less massive
• nebula is the clouds and dust of a star that is forming a new star
• supernova happens when a star dies
• blackhole forms when massive stars collapse at the end of their life
• nuclear fusion is a way of getting stars energy
• what is the patterns in the sky called?

  constellations
• a pattern of stars that are not constellation. EX. big deeper is called what?

  asterism
